the mass of an atom is concentrated in a very small central portion of the atom which is called the atomic nucleus. The atomic nucleus is made up of nucleons, of which there are two important fundamental types: electrically positive protons and electrically neutral neutrons. So the Answer for the question is: Neutrons and Protons.

What is the atomic mass of OH?
The hydroxide ion (OH⁻) consists of one oxygen atom and one hydrogen atom. The atomic mass of oxygen is approximately 16.00 amu, and the atomic mass of hydrogen is about 1.01 amu. Therefore, the atomic mass of the hydroxide ion is roughly 17.01 amu.
Does an atom of aluminum and an atom of gallium have the same atomic mass?
No, an atom of aluminum and an atom of gallium do not have the same atomic mass. Aluminum has an atomic mass of approximately 26.98 atomic mass units, while gallium has an atomic mass of approximately 69.72 atomic mass units.
How do you determine the atom the atomic mass of an atom?
Proton + Nuetron = Atomic Mass
What is the atomic mass of an atom?
The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
How is atomic mass affected by an alpha particle?
The atomic mass of an element decreases when it emits an alpha particle. An alpha particle consists of two protons and two neutrons, so when an atom undergoes alpha decay, it loses these four nucleons. This results in a decrease in the atomic mass number by four and the atomic number by two, transforming the original atom into a different element. Consequently, the atomic mass of the resulting atom is lower than that of the parent atom.
Is the atomic mass and number the same thing?
No, the atomic mass consists of protons, but the atomic mass consists of both protons and neutrons.
What does the mass of an atom consist of?
The mass of an atom consists of protons, neutrons, and electrons. Protons and neutrons are located in the nucleus and contribute most of the atom's mass, while electrons, which have a much smaller mass, orbit around the nucleus.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
The mass of an atom usually expressed in atomic mass units is its?
Atomic mass
The relative atomic mass of an atom can be found by comparing the mass of the atom to the mass of?
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
What does atomic mass represent of an element represent?
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
What is the atomic mass of an oxygen atom?
The atomic mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994
